#![ cfg(not( target_arch = "wasm32" )) ]

// Tested:
//
// - ✔ current_rt for localpool
// - ✔ current_rt for threadpool
// - ✔ current_rt for after spawning it should be a threadpool
// - ✔ rt::block_on
// - ✔ rt::block_on with a boxed future
// - basic methods like spawn and init are being tested in the other integration test files
